PORTABLE LIGHT.

Specification of Letters Patent.

Application filed .Tune 3, 1913. Serial No. 771,485.

To r/[Z whom. it may concern:

Be it known that we, LYMAN JoiiN STARR and lVAL'ri-:ii Hiiznirrinii lViii'i'i-i, both citizens of the United States, residing at Kenosha, in the county ot' Kenosha and State of lVisconsiii, have invented certain new and useful Improvements in Portable Lights, of which the following is a specilication.

This invention relates to improvements .in portable lights, and refers' more specifically to improvements in the shell construetion of the lamp body and reflector.

The salient object of the invention is to provide a construction in which the outer shell, the internal reflector and a front end marginal finish simulating a door are formed essentially of two sheet metal stampings.

Another object or' the invention is to provide in such a structure extremely simplel and convenient means for holding the parts reliably assembled and capable' of being readily disassembled so as to afford access to the space between the shells; to provide extremely simple andetlicient means'for so inserting the glazing and removably holding it in place as to insure a practically airtight closure, susceptible, however, ot' being instantly`v opened; and in general, to dispense Withthe door frame structure heretofore regarded as indispensable in portable lamps of this general character, without either sacrilicing the appearance, efficiency or convenience of the device.

To the above ends the invention consists in the matters hereinafter described, and

more particularly pointed out in the appended claims. i

In the drawingl4`igure 1 is a front elevation of a lamp embodying our invention; Fig. 2 is an axial section ofthe saine; Fig. 3 is a sectional detail, 4With parts shown in perspective, showing particularly the front rim construction. y

.The relative low cost and nevertheless structural efficiency of die-drawn sheet metal parts in portable lamp constructions is thoroughly understood in this art, it has therefore been customary to make lamp. body shells and` door' rims of sheet metal stampings. l

For numerous reasons it has heretofore been regarded as essential to provide'the front ends of lamp bodies of the headlight typewth. either a removable or hinged door 'of manufacture effected but the efficiency frame forming a nishing front rim cai'- rying the glazing. It is obvious that access must be had to the interior of the lamp for various reasons. Heretofore such access has been provided by the front door structure mentioned. The construction and fitting of the front door of suoli a lamp of the headlight type represents a vlarge proportion of the total cost of the lamp. In accordance Wit-h our present invention We have adopted a structure which eliminates the necessity oi a front/door as suoli, and while providing for a perfect simulation of the conventional appearance of a door, and providing for an e icient glazing seat holding the front end glazing, is nevertheless integral with the main body shell members. By such construction not only is a great saving in cost of the lamp as a structure is in no Wise impaired. y

Referring to the drawing, l designates as :i Whole an outer inclosing shell, 2 an internal metal reflector, and 8 the front glazing. The outer shell l is in the present instance of outwardly convex or semi-oval form, but it will, of course, be understood that this shape may be varied so long as the shape adopted be such that it is capable of being drawn or formed from sheet metal.

In the preferred construction shown the front edge of the shell 1 is provided with an outwardly curved molding-like portion 4, integral with the main. body of the shell and provided near its ed e with a circumferential outstanding bea 5 and approximately cylindric liange edge 6. The bead 5 constitutes a retaining and stiiening rib, and the flange 6 in;l conjunction with the adjacent side of the bead forms an angular seat 7 against which the other main member of the lamp fits. The refiector shell 2 is as to its main internal portion of suitable shape to properly reliect forwardly the lightffrom the lament 8 or other lighting element,- eing shown in the present instance ,as/.of the parabolic reflector type. At its lfront end this rellector shell is provided with an nitegral rabbet 9 to receive the .edge ofthe. glazing 3 and outside and adjacent this rabbet with a radially outer/bead-link portion 10, the interior 11 of Which/forms a retaining ring seat, yand still 'farther outside of.
